Application filed April 3, 1902. Serial Noa 101,246. (No model.)

To a/ZZ whom, it may concer-72,:

Be it known that I, WILLIAM A. KING, a citizen of the UnitedStates,residing at Pierre, in the county of Hughes and State of SouthDakota, have invented certain new and useful Improvements inSelf-Heating Branding- Irons; and I do declare thefollowing to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains` to make `and use thesame.

My invention relates ,to a self-heating branding-iron designed forpusinggasolene or other fluid hydrocarbon fuel and adapted to be employedgenerally for stamping, branding, and for other analogous purposes forwhich a heated iron is required.

The device is especially designed for use in branding cattle; butprovision is made for attaching any desired form' of branding-ironthereto.A

The object of the inventionis to providea device of this character whichis simple, durable,.and effective in construction and wherein the partsare so combined as to secure an effective consumption of the fuel and toprovide an easily-operated and compact forni of tool. Y

With this and other minorfobjects in View the invention consists ofcertain novel features of construction, combination, and ar.- rangementof parts, as Willbe hereinafter more fully described,`and particularlypointed out in the appended claim.

In the accompanying drawings, Figure 1 is a side elevation of aself-heating brandingiron embodying my invention. Fig. 2 is a Verticallongitudinal section of the same.

reservoir for supplying air under pressure tou the tube while the innerend of said tube is threaded onto one of the reduced ends 2 of acoupling 3. Inside the tube 1 is arranged a second tube 4, having alongitudinal partition 6, forming induction and eduction passages 7 and8 in communication through a port 5 at the outer end of said tube 4. Thetube 4 thus forms, in effect, a tube, attached at one end to thecoupling 3 and extending to near the rear end ofthe handle 1 and thenbent centrallS7 upon. itself and having its other end open and extendingto near the forward end of the handle 1, thereby forming an indirectpassage between the reservoir and feed-passage 10. By this constructionthe column of liquid hydrocarbon flowing to the burner is red'uced'andis first caused to flow rearwartlly4 through the passage 7 and thenforwardly through the passage 8, by which it is caused to feed more orless regularly and not by spasmodic jets or pulsations, as would betheicase were the passage 10 in direct communication with the reservoir.PassageS is provided with a nipple 9, which screws into a longitudinalfeed-passage 10 in the coupling 3. Into the opposite reduced end 11 ofthe coupling 3 is Hthreaded a generating tube or pipe 12, which is 'incommunication with the said passage 10 and is connected at its forwardend to the base portion 13 of a Bunsen burner 14. A threaded collar ornut 15 engagesthe end 10 of the coupling 3 and surrounds the tube 12.This collar or nut contains packing 16 to prevent leakage of thehydrocarbon. The said base portion 13 of the burner 14 is provided witha feed-port 17, through which the vaporized hydrocarbon passes into theburner-chamber, and this port is governed'bya needle-valve 18,`whosestem 19 extends through the tube 12 and is rigidly screwed or otherwisesecured at its rear end in the coupling3. An annular knurled knob orhandpiece 20 is secured to the tube 12 between said coupling and theburner and is employed for turning said tube to regulate the supply offuel tothe burner. By holding the handle 1 firmly in one hand the tube12 may be screwed in an inward or outward direction in the coupling 3,thereby moving the port 17 toward or from the valve 18 to cut off andregulate the feed of fuel to the burner Vas required. t.

The burner 14 consists of a tube having a combustion-chamber 21 open atits outer4 end and provided with air-ports 22. At itsouter end theburner is threaded, as shown at 23, to receive the branding-iron to beheated. A bulb or cup 24 is secured at its rear end by a Ioo ring 25 tothe burner-hase and Surrounds the rear portion of the burner. This cupis open at its forward end and is adapted to receive a supply of alcoholor gasolene to preliminarily heat the burner and gen erating-tnbe tostart the generation of gas.

In operation the base of the burner and the tube 12 are heated from theburner, which also heats the iron, and the gasolene passing therethroughis converted into gas or vapor, which admixes with the air and passes tothe combustion-chamber, where it is consumed. The amount of gas fed tothe burner and the heating of the iron may be regulated by adjusting thehandpiece 20 in the manner here tofore described.

It will thus he seen that my invention pro- Vides a simple, compact, andconvenient de vice which is readily handled and may he employed forheating branding irons of all kinds.

IVhle the preferred embodiment of the invention is herein disclosed, itwill of course be understood that changes in the form, proportion, andminor details of construction of the parts may be made within the scopeof the invention without departing from the spirit or sacrificing any ofthe advantages thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s-

In a self-heating iron of the character set forth, the combination of atube forming a handle and a hydrocarbon-reservoir, a burner having afeed-port, a coupling connected to the reservoir and having afeed-passage, a cond noting-tube arranged within the handle and havingone end communicating with said feed-passage and thence projectingbackwardly to near the rear end of the tube and thence being bent uponitself and having its opposite end open and extending forwardly to nearthe front end of the handle, thus forming a restricted indirect passagefor the flow of the hydrocarbon from the handle to the feed-passage, agenerating-tube adjustably connected to the coupling. and carrying theburner, a valve governing said port and having a fixed position, andmeans for adjusting the generating-tube to move said port toward andfrom the valve, substantially as described.

In testimony whereof I have hereunto set my hand in presencelof twosubscribing witnes-ses.

WILLIAM A. KING.
